Hi

it is most likely the MAF sensor or air mass sensor these are the exact symptons you get when they start to fail, it is worth a mention though that you may be able to clean the it and they often last a while longer, if not they are pretty cheap even for a porshe.

Do you need more info?

Regards

Dan

Toyota hiace 1982 18R motor not starting when cold


Sounds like the automatic choke is not functioning properly. Take off the air cleaner before starting on a cold day. Looking into the carburetor, the round choke plate should be nearly closed. If not, check the linkage to see if it is disconnected or hanging up on something. If it is OK, look down the carburetor with the chock plate held open, operate the throttle linkage and see it it shoots a stream of raw gas down the carburetor. If not, the accelerator pump will need to be replaced. That stream of gas aids in starting when cold and in acceleration (as opposed to a gas in mist form that it idles and runs on). An accelerator pump is included in a Carburetor kit and usually looks like a round flat rubber diaphragm.

Why does my 1998 sebring idle fine but sputter badly under load.


Does it use spark plug wires or individual ignition coils for the each plug?. My 98 intrepid uses coils and occasionally I have to change them out cause it would start to miss when normal temperature was achieved. If it uses wires, try replacing them, along with the spark plugs.

1998 Dodge Dakota radiator fan does not shut off


.if your truck is over heating with a temp. higher than the normal whicjh supposedly, then the fan keeps on. but if the temperature of your engine is normal when you look at the gauge, then the thermostat attached to the engine below it is fine.
The problem as we go back that your fan keeps on turning, even though your getting a normal temperature., probably get new coolant temperature sender sensor.
To check your temperature sender disconnect the plug from the sender and test it using an ohm meter. When the engine is cold you should have infinite resistance. Then run the engine untill it gets warm. Shut off the motor. Disconnect the plug from your temperature sender and check the resistance again. It should no longer be infinite ( see your repair manual for the correct reading).

When turn on the car in the morning, i accelerate and the revolutions up to 6,000rpm normal. In 3 minute when the car up the motor temperature to the normal operation, i accelerate and the revolutions up...


To begin with, if you are revving a cold engine to 6000 RPM, you are asking for a blown engine. Most OBD vehicles are equipped with a rev limiter that will cut off fuel at 3000 to 4000 rpm to prevent you from over-revving your engine and blowing it up. If yours is revving to 6000 RPM cold, then the rev limiter, for some reason is not working while it is cold. I have no explaination for this. The best thing I can tell you is to stop revving your engine so high when it is cold unless you really want to see what an engine looks like after is has gone off like a grenade.

I have a 1998 Saturn SL2 DOHC with ~140,000 miles. The car runs great, but I am having trouble with the coolant temperature. When first starting the car up in the morning, the coolant temperature gauge...


When you said you replaced everything, did that include the temperature sending unit?
The temperature sensor just operates the cooling fan or fans for the radiator.
The temperature sending unit operates the temperature gauge in the dashboard. If that thing is faulty, the gauge won't work right.
If you did change the sending unit, it could be possible that the computor is screwing it up, but in my 41 years as a mechanic I never heard of it, when a computor goes, nothing works.

What is the temp for overheating ? My boxster is having around 110c during a hot day


Normal engine operating temperatures are typically in the range of
75 - 90 Degrees C. 110 C is certainly overheating.

Porsche boxster 1998 overheats very easily


it could be the thermostat has gone bad-does top hose get hot if no then likely bad thermostat, water pump is bad if pulley is wobbly it is bad, radiator is clogged with corrosion, look in rad when cold and if it is dirty or milky it needs flush and refill with new antifreeze

Motor hesitation only when it is cold once engine is warmed up engine runs smooth. Motor hitches terrible until tempature comes up too normal operating temperature. Once engine is warm it runs perfect,...


It might be your ECT sensor (engine coolant temperature sensor). Usally you can mesure the resistance and the voltage of the ECT sensor. You need a chart which says the Resistance versus the Temperature versus Voltage. EXEMPLE : at 120celsius, voltage should 0,27volts and the resistance should be 1,18Kohms ...etc. (this is only an exemple)

Momentarily Sluggish Acceleration


Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish problems...my 2 cents... Good luck future auto DIY's

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
Regards,
